My partner is currently going through a divorce. He works in London and owns a property there. At the weekends he stays at my house 150 miles away.. I also own my own property - neither of us consider ourselves to be cohabitating. Our finances are completely separate and we each pay our own bills. My concern is that his ex will try to argue we are cohabiting to increase her settlement. I allow him to keep his car at my house in the week (not practical to keep it in London) though in reality in spends most of its time in the station car park) and he rents a small workshop in the town where I live for his hobbies. He has1 bank account registered to my address - neither of us can remember why he used that. His bank statements show occasional lump sum payments to me which would be for his share of holidays and weekends away.
He has already been asked to confirm I am his long term partner which he has done and as yet no challenge has been made as to whether we are cohabiting but I can see it coming down the line...
As our finances are completely separate we each own our own property and pay our own bills would the fact that he has something registered to my address and spends weekends here make that challenge likely to succeed? Having spent years post my own separation getting myself financially secure I resent having to disclose my finances to his ex.
I am in the same situation as you. ie the partner and have my own property and separate finances. My partner has had to fill in the form E with what she knows about my finances. I have nothing to hide from her or the Court, but the only evidence she has to produce is what she knows ie no documentation. None of this has of course stopped the ex from claiming we have been cohabiting for months, run our businesses together etc. He will just look very silly when it comes to court.
